OIL CAN.

Application filed November 28, A1924. j Seriall No. 752,634.

To all whom t may Concern.' Be it known that l, Fnsi) I. JADnN, a citi-Zen ofthe United States of America, and a resident of Hastings, in thecounty of Adams and State of Nebraska, have invented a new and ImprovedOil Can, ot which the following is a description.

My invention relates to oil cans and particularly to an oil can havingpumping means to forcibly eject a limited quantity of oil in eachpumping operation ot the pumping means.

The general object of my invention is to provide an oil can of theindicated type improved in various particulars with respect to the formand arrangement of the diaphragm, of the pumping means, spout, and thepumpoperating means, whereby to promote eiiiciency and simplicity.

The nature of my invention and its distinguishing features andadvantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a vertical section of an oil can formed in accordance withmy invention;

Figure 2 is a plan view of the thumb lever to operate the diaphragm ofthe pump.

'In carrying out my invention in practice, in accordance with theillustrated example, a can body 10 is provided generally of the usualcylindrical form having .a handle 11. The numeral 12 indicates the cantop and 13 the bottom of the body.

A iexible diaphragm 14 is provided of leather or other suitable materialand the edge of said diaphragm is securely held against the lower edgeof the body 10 by the flanged edge 15 of the bottom 13. A spout isprovided formed in sections, there being an inner section 16 extendingcentrally in the can body 10 from a point adjacent the bottomand'projecting through the cap 12. lThe discharge section 17 of thespout is coupled to the inner section 16 by a coupling nut 18, thescrewing down of which on threaded upper end of section 16 draws the top12 and the bottom 13 tightly in positionso that the said bottom 13tightly holds the edge of the diaphragm 14. Within the nut 18 is a ballvalve 19 above which is a spring 20, said ball seating on the upper endof the spout section 16 and the spring 2O pressing at its lower endagainst said ball and abutting at its upper end against the lower endofthe spout section 17. The lower end of the inner section 16 isthreaded to engage internal threads in a plug 21 extending upwardlythrough the can bottom The threaded lower end of the spout section 16passes through a central hole 22 in diaphragm 14 and it receives a nut23 `above saiddiaphragm so that the edge port-ion of the diaphragm aboutthe central hole 22 is lirmly clamped between said nut 23 and the upperend of the plug 21.

The diaphragm 14 has upper and lower washers 24, 25 extending about thesame outward of the central clamped portion of the diaphragm andterminating atvtheir outer edges short of the can body 10.4 An oil hole26 extends throughv the washers 24, 25 and through the diaphragm 14 andis controlled by a Hap valve 27 secured by a bolt 28 and nut 29, so thatthe valve opens with an upwardk flexure of diaphragm 14 and closes witha downward flexure of said diaphragm or movement toward the bottom 13.An oil inlet hole 30 is provided in a side of the plug 21 to establishcommunication between the chamber in the body 10 beneath t-he diaphragm14 andthe lower inlet end of the spout section 16.

A pump rod or wire 31 is secured at its lowery end to the diaphragm 14said lower end being threaded and passing through the washers 24, 25 andsaid diaphragm. Nuts 32, 33 are provided on rod 31 above and below thediaphragm to bear respectively against the washers 24, 25 for firmlyclamping the rod to the diaphragm. The upper end of rod 31 passesthrough a hole 34 in top 12 and the projecting upper end is operated bya thumb lever 35 having a hole 36 through which said rod 31 passes, therod having a collar 37 threaded thereon below the thumb lever 35 and acap 38 threaded to the rod at the upper end above the lever 35. Rod 31extends freely through a washer 39 seated on the top 12 at aV flaringflange 40 formed on said top. A spring 41 bears at its lower end againstthe washer 39 to maintain `the rsame at all times seated at the opening34 closing the same, said spring at its upper end abutting against thecollar or nut 37. The arrangement is such that a depression of the lever35 will compress said spring 41 and will flex the diaphragm 14downwardly. Upon pressure bein removed from the lever 35 the spring 41wi l raise the rod 31 and restore the diaphragm by an upward llexure.The successive downward and upward movement of the diaphragm 14 resultsin a feed impulse of the oil being brought about since the downwardmovement will force oil from the under side of the diaphragm through thehole 30 to the spout section 36 and past valve 19 to and through thesecured section 17. In the upward movement of the diaphragm the valve 27will open and will admit oil to the chamber in the can body 10 beneaththe diaphragm for the next feed impulse.

The thumb lever 35 has sine arms 42 at the front end, said arms having`lugs 43 directed laterally inward toward each other, said arms 42 andtheir lugs 43 engaging in an annular notch or groove 44 in the nut 18 sothat said nut constitutes the fulcrum of the lever.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein illustrated, since,manifestly the same can be considerably varied without departure fromthe spirit of the invention as defined in the ap ended claims.

Iaving thus described my invention, I claim:

1. In an oil can, a can body, a diaphragm disposed in said body spaced ashort distance from the bottom thereof, a valve controlled opening forthe flow of oil to said space from the space above the diaphragm7 aspout extending into the oil can to the space beneath the diaphragm andin comu munication with said first space, and a rod extending from thediaphragm forwardly through the can body and top and operable to flexsaid diaphragm toward and from the said bottom.

2.
